Open, modern house overlooking lake, mountains

Here's a home for people who like openness, concrete and steel. Seattle architect Eric Cobb designed the house, 1114 32nd Ave. S., in Seattle, which was built in 2009. It's 3,065 square feet, with four bedrooms, 2.5 bathrooms, a family room, high ceilings, heated concrete floors, glass walls that open out and roll up, a big patio, and a heated two-car garage on a 7,830-square-foot lot. It's listed for $1.9 million.
